Problems solved by technology

Since the joints are uneven, it is difficult for the naked eye to "scan and locate" all the contact areas, and it is even more difficult to quantitatively determine the area of ​​the contact area
[0006] (3) It is difficult to accurately locate the rock joint face wall by manual dislocation, and it is easy to cause damage to the face wall, which is time-consuming and laborious

Abstract

The invention discloses an automatic control device for realizing the rock joint contact state. The automatic control device comprises a base, rock joints are placed on the base, the support is erected on the base, two baffle boards are arranged above the support, a horizontal moving guide rail is fixed in the middle of the two baffle boards, a horizontal motor is arranged in the horizontal movingguide rail and performs reciprocating motion in the horizontal direction along the horizontal moving guide rail; the horizontal motor is vertically connected with a vertical moving guide rail, a lifting motor is arranged in the vertical moving guide rail, and can performs reciprocating motion in the vertical direction along the vertical moving guide rail, the horizontal motor and the lifting motor are connected with a digital display control box, and the digital display control box controls the motion postures of the horizontal motor and the lifting motor in the horizontal direction and the vertical direction, and the lower end of the lifting motor is connected with a clamp device. According to the invention, the contact state of the rock joints can be automatically realized, and the contact state of the rock joints can be accurately controlled.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering, and in particular relates to an automatic control device and method for realizing the contact state of rock joints. Background technique [0002] my country's infrastructure continues to develop, especially when construction activities such as water conservancy projects and traffic projects involve rock masses. Generally, a rock mass is composed of rock and joints. Human engineering activities such as excavation / driving (such as blasting, mechanical excavation, etc.) inevitably disturb the original rock, causing the weak link in the rock mass—the joint to produce a certain degree of disturbance, which is manifested as the tension between the two walls. Open, dislocation, reverse and other phenomena. If the external forces are repeatedly disturbed, the rock joints will appear in a series of contact states, that is, from the coupled state to the contact state with different coupling degree...
